It's great to check answers or to see a detailed solution to a problem, i would never pay for an app, but I would pay for this one. And it's been a long time coming now, thank you to the creator of this app this app has not gave me a wrong answer yet mishap is extremely accurate. One of the top 3 best apps I have ever used.
Hands down, the best app I've ever used, this is a useful app and all, it helps me with math homework, but sometimes when I'm using the camera it goes blurry then not blurry then it misreads my problem that I have and it messes it up.
That means that the app is just getting more and more capable. HIGHLY recommend the paid version, too. Sometimes the scanning of the picture doesn't work so you have to take the picture the 2nd time but thats completely fine with me.
